Well, the idea didn't work out, but the point is, the wiki needs to be more full of information about the series. i can't post the links since they get blocked, but the point really is that we need to make the wiki feel more complete, just that...
Do they have ages?
I haven't watched it yet but Komichi seems about 15 while Kao is 8-9. I too am an older sibling with a sister who is actively adorable as Kao.
What do you think?
